A tearful President Barack Obama said Friday he grieved first as a father about the massacre at a Connecticut elementary school, declaring, "Our hearts are broken today." He called for "meaningful action" to prevent such shootings but did not say what it should be."The majority of those who died were children -- beautiful, little kids between the ages of 5 and 10 years old," Obama said.At that point he had to pause for several seconds to keep his composure, and he wiped his eyes.
